Dear All, this series adds support for dual-LVDS panel IDK-2121WR from Advantech: https://buy.advantech.eu/Displays/Embedded-LCD-Kits-High-Brightness/model-IDK-2121WR-K2FHA2E.htm Dual link support is very recent for R-Car Gen3, and I couldn't find much on dual link panels in the kernel either, therefore comments are very welcome to get this right. The panel doesn't come with the EK874 kit, but it's advertised as supported, therefore this series adds a new dts file to support the configuration of the EK874 + IDK-2121WR. Laurent, it appears that Rob has been busy converting the dt-bindings relevant to this series, and his changes are now found in linux-next. Most notably Documentation/devicetree/bindings/display/panel/panel-lvds.txt has now become Documentation/devicetree/bindings/display/panel/lvds.yaml You have already taken patch: https://patchwork.kernel.org/patch/11072749/ as such the patch I am sending you is still related to: Documentation/devicetree/bindings/display/panel/panel-lvds.txt Patch "dt-bindings: display: Add bindings for Advantech IDK-2121WR" is still assuming the format is .txt, as I am not too sure about what the protocol is in this case? Shall we take this patch and convert it later to .yaml or shall I convert it to .yaml straight away? Please, let me know what's the best course of action. v1->v2: * dt-bindings: display: renesas: lvds: Document renesas,swap-data - dropped * drm: rcar-du: lvds: Add data swap support - dropped * drm: rcar-du: lvds: Do not look at ports for identifying bridges - dropped * drm: rcar-du: lvds: Add support for dual link panels - dropped * dt-bindings: display: renesas: lvds: RZ/G2E needs renesas,companion too - taken * drm: rcar-du: lvds: Fix bridge_to_rcar_lvds - taken * arm64: dts: renesas: r8a774c0: Point LVDS0 to its companion LVDS1 - taken * arm64: dts: renesas: cat874: Add definition for 12V regulator -taken * dt-bindings: panel: lvds: Add dual-link LVDS display support - reworked according to Laurent's feedback * dt-bindings: display: Add bindings for Advantech IDK-2121WR - reworked according to Laurent's feedback * drm: Rename drm_bridge_timings to drm_timings - new patch * drm/timings: Add link flags - new patch * drm/panel: Add timings field to drm_panel - new patch * drm: rcar-du: lvds: Fix companion's mode - reworked according to Laurent's feedback * drm: rcar-du: lvds: Add dual-LVDS panels support - new patch * drm/panel: lvds: Add support for the IDK-2121WR - new patch * arm64: dts: renesas: Add EK874 board with idk-2121wr display support - Made some changes Thanks, Fab Fabrizio Castro (9): dt-bindings: panel: lvds: Add dual-link LVDS display support dt-bindings: display: Add bindings for Advantech IDK-2121WR drm: Rename drm_bridge_timings to drm_timings drm/timings: Add link flags drm/panel: Add timings field to drm_panel drm: rcar-du: lvds: Fix companion's mode drm: rcar-du: lvds: Add dual-LVDS panels support drm/panel: lvds: Add support for the IDK-2121WR arm64: dts: renesas: Add EK874 board with idk-2121wr display support .../display/panel/advantech,idk-2121wr.txt | 56 +++++++++ .../bindings/display/panel/panel-lvds.txt | 95 ++++++++++++---- arch/arm64/boot/dts/renesas/Makefile | 3 +- .../boot/dts/renesas/r8a774c0-ek874-idk-2121wr.dts | 116 +++++++++++++++++++ drivers/gpu/drm/bridge/dumb-vga-dac.c | 6 +- drivers/gpu/drm/bridge/sii902x.c | 2 +- drivers/gpu/drm/bridge/thc63lvd1024.c | 2 +- drivers/gpu/drm/bridge/ti-tfp410.c | 6 +- drivers/gpu/drm/panel/panel-lvds.c | 8 ++ drivers/gpu/drm/pl111/pl111_display.c | 2 +- drivers/gpu/drm/rcar-du/rcar_lvds.c | 126 ++++++++++++++------- include/drm/drm_bridge.h | 40 +------ include/drm/drm_panel.h | 3 + include/drm/drm_timings.h | 86 ++++++++++++++ 14 files changed, 439 insertions(+), 112 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/panel/advantech,idk-2121wr.txt create mode 100644 arch/arm64/boot/dts/renesas/r8a774c0-ek874-idk-2121wr.dts create mode 100644 include/drm/drm_timings.h -- 2.7.4
